Construction of transport networks that combine building pathways and roads for evacuation routing and scheduling problem

The availability of route network data is one of the key elements of evacuation route modeling for solving capacity-constrained routing problem; the data must include real-time updates, and routing must be in real-time. We consider the problem of constructing transport network data used for finding routes and schedules for evacuation from urban buildings and out of a predetermined neighborhood. The transport networks involve corridors and stairs in the buildings and road networks outside; there are a predefined set of exit points out of the road network serving the buildings. This paper offers a promising direction for constructing combined networks of buildings and roads using data extracted from GIS databases in conjunction with paths inside buildings, it discusses the process of developing collection of datasets for combined path networks for buildings and roads. Simple pedestrian flow capacity formulas for corridors and roads based on readily available geometric data are developed.
